Base mount
A 2.2 kW air-cooled spindle with an ER20 interface and base mounting. This page covers the base-mount configuration; the same printed code also appears on a housing-mount version.

QUICK DECISION
Where this configuration fits.
Check before ordering
Compare the base dimensions and bolt locations before ordering. The 220 V / 7.8 A and 380 V / 4.4 A winding configurations have separate drawings.
Consider another model
For a cylindrical clamp installation with water cooling, compare the GDZ-23. Its mounting arrangement, speed and cooling circuit differ even though rated power is also 2.2 kW.
Compare the differences →SPECIFICATIONS
Read the operating conditions.
The base-mount drawing specifies 2.2 kW, 18,000 rpm, 300 Hz, ER20 and 7 kg. Overall length is 288.5 mm.

INSTALLATION CHECKS
Match the whole assembly.
Check the base rather than relying on the model code alone. A housing-mount version cannot inherit this page's base drawing or installation dimensions.
- This page is for the base-mount version only.
- Choose the winding that matches the drive output, then check its rated current.
- Request installation files specifically for the base-mount structure.

MODEL QUESTIONS
Before you order.
Does the code identify the mounting arrangement?
Not by itself. The same printed code appears on both base-mount and housing-mount configurations. Confirm the physical structure.
Can I use the 380 V drawing for a 220 V order?
Use the drawing for the selected winding. The current rating differs: 7.8 A at 220 V and 4.4 A at 380 V.
